MY WIZARD SCAR BURNS FOR YOU: Hogwarts is the kind of school that Chicago Public Schools CEO Ron Hubberman is probably glad he doesn’t have to put up with, what with the constant attacks from the Death Eaters, that drugged-out looking Voldemort, and the PTA parents who’d throw a shit storm over Dumbledore’s sexual orientation.

Rowling series, “Harry Potter And The Half-Blood Prince,” which screens at Doc Films. 1212 E. 59th St.; Hyde Park. Saturday at 6:30 p.m. and 9:30 p.m., and Sunday at 3:15 p.m. $5.
